[JSL] Select rows using "Complex" conditions

[#1]

Hello All,

I would like to write a JSL script to select the rows in a table with “complex” conditions:

I need to select ONE ROW per Metric (Column :Metric) with conditions IN ORDER OF PRIORITY:

1- if the condition Flag1 = “FLAG” AND Flag2 = “FLAG” exists, Select Col Max (:Metric1) of this condition

2- if the condition Flag1 = “FLAG” XOR Flag2 = “FLAG” exists, Select Col Max (:Metric1) of this condition

3- Else, Select row Max (Metric1)

Below a tentative code using For Each Row () and a debug column, but my attempt doesn’t work and is not very elegant.

Also, I am not sure how to do an XOR (exclusive OR) in JLS without using combination of basic gates.

Is there a better way to do this?

Note: please find attached a PNG that illustrate my request

Thanks

//This attempt doesn't select the right rows

debugcol = dt << New Column("Debug", Numeric, Continuous);

For Each Row(dt, 

	FLAG_row = 
		If(
			:Flag1 == "FLAG" & :Flag2 == "FLAG",
				Col Max(:metric1, :Metric),
			IF(
				:Flag1 == "FLAG" | :Flag2 == "FLAG",
					Col Max(:metric1, :Metric),
				If(
					:Flag1 == "OK" & :Flag2 == "OK",
						Col Max(:metric1, :Metric)
			)));
	debugcol[Row()] = FLAG_row;
);

dt << select where (:metric1 == :Debug);
